On the "Upload a video" page, near the bottom (under Videos you can currently upload) it says

If a video is not on the list then it will be for one of the following reasons:

-The video's premiere date is in the future.-The video has no listed music.-The video lists no anime source. Anime sources have to be confirmed by the admins so if you entered a new anime then you may want to ask on the forum if it can be confirmed for you.-The video is already locally hosted.

The problem you are running into is that No.6 hasn't been confirmed as anime yet.I've confirmed it for you, so you should be able to get upload permission now.
